...and a new zombies map: Shangri-La, described as "an exotic and mysterious map filled with deadly traps, dark secrets and innovative gameplay that will challenge even the most daring Zombie hunters."

In honor of the new maps, Treyarch will offer a double XP weekend starting July 1.

If you're a PS3 gamer, I'm sorry: You'll have to wait. The Annihilation pack will be released for the PlayStation 3 at a later, unknown, date.
